I have an eclipse 7 with the standard 8cell 600mah battery pack that came with it. I seem to be having trouble keeping a half decent voltage for more than 3 flights. Does anyone else seem to be having this problem? Is the Tx sucking the life outta the batteries or what? Do I have a bad battery pack? I'm thinking that 600mah is just enough to run the Eclipse and I might to better to buy a higher capacity pack.
